|Date Sustainable service logistics for offshore wind farms NWO Call ‘Duurzame logistiek’ Startbijeenkomst, Utrecht, January Prof. Dr. Ruud Teunter (RuG) Dr. Jasper Veldman (RuG) {Prof. Dr. Iris Vis (RuG)} {Prof. Dr. Kees Jan Roodbergen (RuG)}

|Date Offshore wind farms 2

|Date Offshore wind farms: relevance ›13,9% of total EU electricity demand by  Target Netherlands much more ambitious (Green Deal) ›Cumulative investments 211,1 billion euros until ›Annual reduction 315 Mt of CO 2 emissions 2 › fte employment in The Netherlands by ›Operations & maintenance (O&M) 25% of total cost 1 ›Service logistics typically 50% of O&M cost 4 ›40% (O&M) cost decrease needed for profitable wind energy 1 ›Even for 2015 capacity (37.000MW 5 ) and corresponding O&M cost, a 5% cost reduction amounts to 1 billion euros ›Smarter service logistics can help make this energy source truly sustainable 3 Sources: 1 Topteam Energie (2012), 2 EWEA (2011), GL Garrad Hassan (2013), 5 Bilgili et al.

|Date Logistics Network 8

|Date Challenges and sustainability goals addressed within 5 work packages 9 Challenges: Lumpy service demand Multi-material network (spares, tools, consumables) Coordination flows materials and technicians (different transportation requirements) Coordination onshore and offshore flows Uncertainties (e.g. weather) Coordination of return flows Cooperation within and across wind farms Goals: Improving availability Reducing maintenance Reducing waiting time Reducing time spent offshore (and onshore) Reducing transportation

|Date Work packages Buffer and repair facilities design; location decisions; kitting locations; transshipment locations WP 1: Onshore and offshore network design Failure prediction; opportunistic CBM; multiple resource planning; joint service and resource planning WP 2: Planning of offshore service policies Vehicle assignment, routing, timing; storage; kit completion WP 3: Coordination of sustainable service logistics Performance-based contracting, cooperation in diads and triads, multiple wind farms, trust WP 4: Collaboration and governance aspects Robustness, simulation; cross-chain control, implementation WP 5: Integrated logistics operations 10

|Date Knowledge utilization ›Societal and business relevance  Sustainable service logistics research contributes to targeted cost reductions (40% by 2020), reduced CO 2 emissions, reduced risk for workers, economic growth ›Valorisation  Continuous interaction with 12 external partners for brainstorming, discussion, data gathering, model validation, implementation of solutions in business processes - Tool development and Implementation with partners ECN, Oliveira, Eyewind ›Dissemination  Dissemination through workshops, white papers, practical publications, lectures (e.g. Energy Academy Europe) - This will be done with the help of dissemination partners Dutch Institute for World Class Maintenance and Energy Valley 11
